WOOD-GRAINING MACHINE.

SPECIFTCATION forming part of Letters Patent No. 288,302, datedNovember. 18, 1883.

Application filed May 15, 18:93. (No model.)

To (LZZ whom it may concern:

Be it known that I, EDWIN BnILLI-Nc-ER, a citizen of the United States,residing at York, in the county of York and State of Pennsylvania, haveinvented a new and useful Improvement in Vood-Graining Machines, ofwhich the following is-a specification.

This improvement relates to that class of machines in which arollerengraved in relief is made to impress its design upon the material runthrough the machine, the designroller being suitably mounted andconnected with pressurerollers for that purpose.

The object of the invention is to produce a machine in its simplestform, and so arrang ing it that the product of the machine will bedouble of those which have preceded it.

This improvement is more particularly adapted to cigar-box manufacturersuse, a very correct imitation of expensive woods being obtained by theuse of the apparatus.

The drawings herewith forming part of this specification fully disclosethe nature of my improvements, like letters in which designate likeparts in all of the same.

Figure 1 is a side elevation, showing the connectinggearsandfeeding-tables. Fig. 2 is. a

' front elevation, showing part of countershaft,

driving-pulley, and driving-gear, the tables removed; Fig. 3, sideelevation on the driv-- ing-gear side, the tables removed, in all ofwhich A represents the side frames; A, central horizontal jaw for thereception of the design-roller-bearings boxes; A, upper vertical, and Alower vertical, jaws, for the bearing-bores of the pressure-rollers; B,caps to the jaws; 0, screws regulating the pressure upon the rolls; D,brackets for the feedingt-ables; E, feedingtables; F F, pressure-rolls;Gr, design-roll; HQHH, equal connecting gearwheels; I, maindriving-wheel; J, pinion for the same; K, counter-shaft; L, driving-poll'ey; M, pad-bearings for the countershaft; N, the driving-belt.

The construction of the machine is simple, the frames are each cast inone piece, the jaws are planed to size, and the bearing-boxes to Afterplacing the central design-roll in position, the upper pressureroll islet down in the jaws and rests upon a thickness of rubber of about thethickness of the lumber to be passedthroughthemachine.Thelowerpressure-roll' bearings rest upon the cap until theregulating-screws are operated, when they rest upon the same; and theroll is also brought up toward the central design-roll until the spacewill just take the board to be grained between them. The rolls may allbe of metal, or the design-roll of metal and thepressure-rolls of wood.The design-roller is first smoothly turned and polished. It is thenprepared to receive a transfer of the grain of the desired wood to beimitated. The transfer may be made directly from the wood or sketched onby hand. -After the transfer has been made, the spaces betwecn'theleading lines are with proper tools out out, leaving the leading linesprojecting from or in relief upon the surface of the roll.

Theoperation of the machine is as follows: Having been adjusted asdescribed,-the lumber,previously planed to thickness, is placedconvenient to the machine. Two operators are required, if the machine isto be worked to its full capacity, or if the lumber is to be grainedupon both faces. 4 The lumber is first fed in from the rear table,between the design-rolland upper pressure-roll, is received by theoperator at the front, dropped upon the lower table, and passes betweenthe design-roll and lower pressure-roll. In this case the lumber isgrained upon both faces, the lower face being grained in its passagefrom the rear'to the front, and the upper face in its passage from thefront to the rear ofv the machine. For single-face graining, ungrainedlumber would be placed at both front and rear of the machine, andeachoperator would insert an uugrained and remove a grained piececonsecutively. I prefer to perform the operation of graining before anycoloring is applied to the wood, the coloring and polishing of the woodbeing subsequent-1y performed in special machines for that purpose. V

VVood-graining machines and rolls in themselves are not new, and arefully described in several patents, specifically in No. 238,181,February 22, 1881, E. Struppe, wood-grain ing machinery, in which thegraining-roller is composed of a series of alternating diskcutters andwashers secured upon a spindle by lock-nuts, and provided with a singlepressure-roll, which maybe placed indiffer ently above or below thegraining-roll, and which thereby limits the quantity of lumber grainedto what may be entered between the tween the upper pressure and grainingroll at one end ofthe machineand between the lower pressure and grainingroll at the opposite end of the same, and the consequent doubling of theproduct of the machine. I believe, therefore, that my mode of doing thesame, and the rapidity with which it may be performed by the use of myimprovement, is an advance in the art.

Havingfully explained the construction and operation of my improvedgrainer, I desire to secure by Letters Patent the following claimsthereon:

1. A wood-graining machine comprising the following elements: frameshaving each one central horizontal jaw and upper and lower verticaljaws, provided with suitable bearing-boxes, and caps with adjustingpressure-screws, a central graining-roll, and upper and lowerpressure-rolls, suitable connecting and driving gear, withcounter-shaft, pinion, and pulley thereon, substantially as shown, andfor the purpose set forth. 7

2* In combination with a graining-machine frame, as described, thebrackets D and tables E, the central graining-rolL'G, and pressurerollsF F, gears H I J, shaft K, and'pulley L, whereby the machine is madedoubly operative, substantially as and for the purpose set forth.

3. In combination with a graining-machine frame, as described, thecentral graining-roll, G, constructed as described, movably fixedcentral to two equal-sized pressure-rolls placed vertically andadjustably, one on each side of said central roll, connected by suitablegears, H, and arranged to be driven by gears I J, and pulley L on shaftK, substantially as and for the purpose specified.
